Elisabeth Sage ’19 knows a thing or two about wrestlers and their eating habits.

“I have grown up in a family of wrestlers,” Sage said. “I have had to adjust my life for my family members who are wrestlers, in terms of not eating around them or cutting weight when they are cutting weight.”

She’s looking at the risks of cardiac death for men, especially male collegiate athletes, in weight-pressured sports (wrestling) who participate in maladaptive-eating behaviors such as fasting, water reduction, sauna use, cutting down on proteins, or cutting out electrolytes.

“There has been research on sudden cardiac death in athletes and maladaptive eating disorders in athletes, but no one has put the whole triangle together–whether the eating behaviors are causing the sudden cardiac death or are a moderating factor,” Sage said. “That’s what I’m looking at is weight-pressured sports, maladaptive eating behaviors, and cardiac risks.”

Sage finished working with her final few test subjects at the end of the school year, and now she’s analyzing the data. Sage’s 61 subjects were placed into one of three categories–NCAA athletes in weight-pressured sports (wrestlers), NCAA athletes in non-weight-pressured sports, and non-athletes. Each person participated in a 45-minute session in which Sage took their heart rate, cardiac functions, blood pressure, and body mass index. Subjects also filled out a survey.

“I’m specifically looking at a couple of cardiac factors, including decreased R wave amplitude (decreased force of the contraction of the ventricles of the heart), which has been shown in eating disorder patients, and prolonged QT intervals, which looks at if it’s taking longer for the heart to go through its whole circuit,” Sage said.

Sage said the results could also help enforce healthy attitudes in wrestlers because cardiac markers don’t lie.

“It’ll be helpful in terms of creating regulations and interventions. If someone has an eating disorder or is showing maladaptive eating behaviors, an athlete could easily lie to a doctor about symptoms, but research has shown that these cardiac markers improve when their symptoms improve,” Sage said. “So it’s a way to physically check whether they are making changes.”

Professor Melinda Green said Sage has been working ahead throughout her career at Cornell. In fact, she started this Senior Honors project the fall of her sophomore year.

“She has always been about a year ahead of her trajectory, taking many classes early,” Green said.

Sage hopes to become published with the results of her research.

“It’s exciting to know that if I do discover significant findings, it’s going to be groundbreaking,” Sage said.
